Abstract

Transition duct assemblies and gas turbine engine systems involving such assemblies are provided. In this regard, a representative transition duct assembly (120) for a gas turbine engine (100) includes: an impingement sheet (124) having cooling holes (140) formed therethrough, an inlet end (142) and a non-flanged outlet end (144), the impingement sheet being operative to be positioned about an exterior of a transition duct (127;190) such that cooling air is directed to flow about the transition duct; the non-flanged outlet end of the impingement sheet being operative to attach the impingement sheet to the transition duct such that the inlet end is positioned adjacent to an intake end of the transition duct and the outlet end is positioned adjacent to an exhaust end of the transition duct.
